muRata UCE-2.5/20-D48NB-C

Units are offered with fixed output voltages from 1.5 to 12 Volts and currents up to 30 Amps. UCEs operate over a wide temperature range (up to +85 degrees Celsius at moderate airflow) with full rated power. Interleaved synchronous rectifier topology yields excellent efficiency over 90% and no reverse output conduction. UCEs achieve these impressive mechanical and environmental specs while delivering excellent electrical performance in a through-hole package. Overall noise is typically 50 mV pk-pk (low voltage models) with fast step response. These converters offer tight output regulation and high stability even with no load. The unit is fully protected against input undervoltage, output overcurrent and short circuit. An on-board temperature sensor shuts down the converter if thermal limits are reached. “Hiccup” output protection automatically restarts the converter when the fault is removed. A convenient remote On/Off control input enables phased startup and shutdown in multi-voltage applications. To compensate for longer wiring and to retain output voltage accuracy at the load, UCEs employ a Sense input to dynamically correct for ohmic losses. A trim input may be connected to a user’s adjustment potentiometer or trim resistors for output voltage calibration. The UCE will tolerate substantial capacitive loading for bypass-cap applications. UCEs include industry-standard safety certifications and BASIC I/O insulation provides input/output isolation to 2250V. Radiation emission testing is performed to widely-accepted EMC standards.

• For efficient, fully isolated DC power in the smallest space, the UCE open frame DC-DC converter series fit in industry-standard “eighth brick” outline dimensions and mounting pins (on quarter-brick pinout).
